DRILLING- MACHINE.

SPECIFIOATION forming part of Letters Patent N 0. 596,558, dated January 4, 1898.

Application filed May 5, 1896. Serial No. 690,368. (No model.) I

To all whom it may concern:

Be it known that I, WILLIAM VAN WAG- ONER, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Drilling-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is an'elevation, partly in section, of my improved drilling-machine, a portion of its supporting-frame being broken away. Figs. 2 and 3 are vertical sections taken, respectively, on lines 2 2 and 3 3, Fig. 1. Figs. i and 5 are horizontal sections, partly in elevation, taken, respectively, on lines 4 4 and 5 5, Figs. 1 and 3; and Fig.6 is an elevation of the detached friction-piece for holding the tool-carrying spindle in its elevated or inoperative position.

A represents the supporting-frame, B the base, 0 the table, and D the tool-carrying spindle, of my improved drilling-machine. The lower end of the supporting-frame A is preferably formed cylindrical, and the base B and the table C are respectively provided with split collars b c, which are arranged one beneath the other upon the lower end and central portion of said supporting-frame and are clamped in their adjusted position by suitable screws or other clamps b c. The upper end or head of the supporting-frame A is provided with a forwardly-extending offset a and substantially parallel forwardlyextending arms a a which form bearings for the toolcarrying spindle D. Said upper end or head of the supporting-frame A is also preferably provided with a rearwardly-extendin g arm a formed with a lengthwise socket a for receiving the cylindrical end of a movable arm at, which is held in its adjusted position by 'a screw or other clamping device a, that is longitudinally adjustable in the arm a and projects into the socket c}. The opposite or free end of the arm a is formed with a lateral extension a which supports a spindle or shaft a provided with a pair of pulleys a for guiding a belt (1, that is preferably utilized to drive the spindle D; When the belt (I extends downwardly from a plane above the pulleys ed, the arm a is arranged so that its lateral extension a extends upwardly, as seen by full lines at Fig. 1, and when the belt (:1 extends upwardly from a plane beneath said pulleys a the arm a is rocked to its position indicated by dotted lines at said figure.

The tool-carrying spindle D is reciprocat-ed longitudinally by any suitable means, presently described, is revolved by the belt at or any other desirable driving mechanism, and is preferably so arranged and connected to said driving mechanism that when reciprocated it is automatically thrown into and out of action. The spindle D is preferably provided with a loose pulley d, arranged above the arm a and a pulley d of substantially the same diameter as the pulley d, beneath the arm a, arranged above said pulley d and suitably fixed to said spindle. The pulley d is arranged in front of the rearWardly-extending arm a and the pulley a and the belt (1 is normally movable around said pulley d. As the spindle D is alternately depressed and elevated the belt d passes from the pulley d to the pulley (Z and vice versa, and thereby eifects revoluble movement of the spindle D and permits said spindle to remain idle.

The means for reciprocating the spindle D preferably consists of a rocking spindle E, provided with a pinion e, meshing with teeth upon a sleeve 6 surrounding the spindle D and prevented from revoluble movement by any suitable means. (Not illustrated.) A suitable actuating-wheel e is usually fixed to one extremity of the spindle E and is provided with a hand-lever e The inner face of the actuatin -wheel e is preferably formed with a socket c and arranged therein is a friction-piece F, having its adjacent face engaged With the outer face of a boss or hub projecting from the supporting-frame A. The friction-piece F is preferably formed concavoconvex in cross-section,as clearly seen at Figs. 3, 5, and 6, and is adjusted toward and away from the adjacent face of the frameAbysuitable adjusters, here illustrated as screws f,re ciprocally movable in the hub of the wheel 6 on opposite sides of the spindle E. The frictional engagement of the friction piece or Washer F with the adjacent face of the frame A is readily varied by the adjusters f and is normally sufficient to hold the spindle D in its elevated position Without necessitating any other similar device for this purpose.

The operation of my invention will now be readily understood upon reference tothe foregoing description and the accompanying drawings, and it will be particularly noted that the same is simple in construction and facilitates rapid drilling owing toits ready manipulation and the means for automatically connecting and disconnecting the toolcarrying spindle and its driving mechanism.
